SHINGLE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 276,412, dated 4April 24, 1883. Application led August 9, 1882. (No model.)

To all whom it may concern: l

Be it knownthat I, PLEASANT ROOKWELL HOUPE, of Oak Forest, in the county ofA Iredell and State of North Carolina, have invented a new and useful Improvement in Shingle-Machines, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, forming part of this specification.

This invention consists of means for adjusting the head-block or feed-bar on the carriage Of a shingle-sawing machine.

In shinglesawing machines it is common to provide a carriage with parallel rack-bars for graduating the adjustments of a head-block or feed-bar; but heretofore the means provided for connecting the head-block with the rackl between said parts.

bars have been adapted for that purpose only, while the head block required additional means of adjustment, such as a secondpairv of rack-bars connected thereto, and a series of connected levers, requiring means, also, for their adjustment.

Now, the object of my invention is to provide means for connecting the head-block with the rack-bars, which shall be adapted, also, to regulate the adjustments of the head-block, to the end that as few and as simple mechanical expedients shall be required as possible.

In the drawings, Figure l is a plan view of my invention, showing the internal construction of the head-block. Fig; 2 is a side elevavation, and Fig. 3 is an end elevation, of my invention, showing the connection between the carriage and the head-block.

The carriage A, which is to he supported upon rollers to adapt it to bemovcd with ease along a suitable track, is provided with cleats b b near its ends, with which corresponding "i cleats, c c, on the head-block B are adapted to engage to form a laterally-sliding `connection The head-block B is in the usual manner made with an internal chamber, C, open at the ends, in which are placed two oppositely-arranged bars, d d, having shoulders c, which .project without the ends of said chamber, and pivoted to a common lever, D, at points on opposite sides of the pivot f of said lever. The shoulders c are provided with dogs g, consisting of serrated plates secured thereto in such manner that they shall project inward toward each other to adapt them to enter the ends of the bolt which is to be sawed into shingles, and the 1ever D projects through a slot in the rear side of the head-block, in order that it may be oscillated to operate the dogs. A single move- .ment of the said lever will move both dogs simultaneously, either toward or from each other.

At each end of the carriage Ais provided a rack-bar, E, arranged parallel with the cleats b b, and latches h h, which are pivoted to the head-block, near its ends, are adapted to engage with the rack-hars to hold the headblock in a given position; and they are also adapted to serve as levers in moving the ends of the head-block alternately forward in the adjustment of the bolt to the saw.

The device is operated in the following manner: A holt to be sawed is laid upon the carriage in contact with the head-block, and is secured to the head-block by means of the lever-operated dogs. The head-block is then adjusted in proper position to enalhle the saw to take olf a portion of the bolt suflicient for a shingle. Previous to each operation of cutting a shingle one end of the head-'block is adjusted, by means of one of the latches h, toward the saw to give the necessary Obliquity to the bolt to secure the usual wedge-shaped shingle, and the ends ofthe head-block are adjusted alternately, so that the butt of the shingles shall be formed first at one end and then at the other of the bolt, to reduce thelatter uniformly in the operation of sawingitinto shingles.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1st The combination of the carriage having a rack-bar at each end, and the head-block adapted 'to slide laterally in engagement with the carriage, and having latches orl levers pivoted thereto at points between the rack-bars, and extended across and engaging with the rack-bars, respectively, substantially as shown and described.

PLEASANT ROCKWELL HOUPE.
